CHARLES R. MlILLEB, OF WHITESBORO, TEXAS.

EXPLOSION-ENGINE STARTER.

Specification of Letters Patent.

Application filed September 2 8, 1914. Serial No. 863,935.

To all whom it may concern. 4

Be it known that I, CHARLES R. MILLER, a citizen of the United States, residing at lVhitesboro, in the county of Grayson and State of Texas, have invented a new and useful Explosion-Engine Starter, of which the following is a specification.

The present inventionrelates to improvements in explosion engine starters, one object of the invention, is the provision of a mechanical starting mechanism adapted to displace the ordinary hand crank upon explosion engines either in an automobile or marine engine, the same when attached to the automobile being readily operable by the chauffeur or operator from his seat, and being thrown into operation by the foot and operated by hand to impart the necessary rgta ion at the initialstarting of the crank s aft.

is the provision of an attachment adapted to be connected to the frame'of an automobile to be placed into and'out ofcperation with the crank shaft of the engine, the mechanism including a worm or spiral in combination with a. surrounding frame disposed for reciprocation relatively to the wormor spiral to impart the desired rotation thereto at the initial starting of the crank shaft.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combi nation and arrangement of parts and in the kletails of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invenLon herein disclosed can :be made with in the scope of what is claimed without departing from the spirit of the invention.

- In the drawingsFigure 1 is atop plan.

partially diagrammatic of an automobile showing the present invention applied thereto. Fig. 2 is a top plan view on an enlarged scale of the device adjacent the crank shaft engaging portion of the engine. Fig. 3 is a front elevation thereof. Figs. 4, 5 and 6 are detail views of various parts thereof.

Referringto the drawings, E designates the" engine, mounted and supported from the automobile frame 1, the crank shaft 2 thereof being provided with the crank operating end 3 which is adapted to be engaged by the reduced member 4 which is carried upon the rotatable and longitudinally slidable shaft 5. This shaft is journaled in the frame '6, which when the present device is adapted to be used with an automobile of the Ford type, is attached as at 7 to the bosses thereof. Attached to the forward end of the shaft 5 are the two nuts or washers 8 which cooperate with the ball bearing member 9 to takecare of the thrust of the shaft 5, when the same is'inoved to be placed in engagement with the crank shaft of the en gine. Formed upon or carried by the shaft 5 intermediate of its ends, is the sleeve 9' provided with the two spirals 10 which thus provide an abutting means to cooperatewith the anti-frictional rollers 11 supported; radially upon the pins 12 within the annulus 13. This annulus 13 is provided with two pairs of oppositely extending pins 14, upon each of which is mounted, the anti-frictional roller 15 while attached upon the pins 14 tional rollers 15 so that the annulus 13 may t be reciprocated thereonwith the least possible friction.

In order toprovide"a 'means'for reciprocating the annulus 13, connected to the two respective apegtured. lugs 17 are the two rearwardly extending rods 18. The rear ends of these tools 18 are connected to the cranks 19 of the transversely mounted shaft 20. Also connected to the cranks 19 and extending in a rearward direction, are the springs 21 whose rearends are attached to the frame of the automobile as at 22.

In order to provide a. means for rotating the shaft 20 and consequently cooperating with the s rings 21 to reciprocate the annulus 13, an thus impart the desired rotation through the spiral or worm member 9 t0 the shaft 5, the ratchet wheel 23 is fixed to the shaft 20 at one side and is operated by the manually controlled. lever 24 carrying the manually released pawl 25. It will thus be seen that when the lever 24 is oscillated and through the pawl 25 and the ratchet 23 has imparted the desired rotation to the shaft 20, the cranks 19 will slide the annulus 13 forwardly and rotate the shaft 5. As'the annulus is placed in the position so that when the foot lever or treadle 26 is depressed it places the crank shaft engaging, member 4 in engagement with the starting crank operating end 3 of the crank shaft of Patented Mar. 30. 191 5.

, and properly spaced therefrom, by the en- A further object of the present invention,

gme, having a starting crank receiving cona the engine, the'springs 21 due to the continued rotation of the shaft 'and the manual release of the pawl *from' the ratchet 23 will assist in rapidly moving the. annulus 13 5 to the rear 0r towardtheengine, and thus the rollers 11 will cause thespiral member 9 to be rotated and l otate the shaft 5 to impart the desired rotation at the initialstartipg of the crank of the engine.- It will thus 10. be "seen that the cranks 1 9 are operated to move the annulus 13 in its extreme forward position before the shaft '5' is slid toward I V the crank shaft of theenfgine to cause the same to be engaged. thereto 1' 5 nwin thus be Seen that with this on:

- struction, that the enginemay be cranked without the operator leaving his seat, and that the springs may be of such a'strength ,as to impart the desired sliding movement l-to the annulus .13 to causethe' starting shaft 5 to be rotated and when connected with the engineshaft, operate the engine shaft at the initial starting ,thereof. f What is claimed-is:

1. The combination with an explosion ennection, 0f a starting device, including a frame, .a' longitudinally slidable ,rotary shaft mounted in-the frame, means carried 3 upon one end thereoffor engagement with the crank receiving. means of the engine, a

member carrying a spiral fixed to the shaft Y within the frame,- an annulus surrounding e the shaft andslidably mounted within the 3 frame, said-annulus being held against rot ary movement, means carried by the annulus forengagingpthe spiral, two rods connected to the annulus, a transverse shaft having twocranks, each crank being con:

shaft and the annu us to nscted to its respective.rod, means for rotating the transverse shaft toreciprocate the annulus, and a spring connected to the transverse shaft for operating said transverse shaft and the annulus to impart rotation to the longitudinally slidable rotary shaft. in engine starting direction.
